Can you bore a Harrell's tuner that much?
Supposed to be able to go to 1.016
It will depend on how it shoots bare barrel. if it has very little vertical now then less weight will be needed. remember the highest POI it can now shoot without a tuner is what you will want with a tuner. put simply bullet exit from the barrel should be at the top or pointing up rather than down.
Thanks Lee. Right now it is shooting pretty well. Just wanted to try a tuner to see if I could tighten it up a little. I will try the the Harrels and go from there.
Well it’s close to but not that small with some ammos
If it does shoot good, then you probably need a tuner not more than 4.250oz. maybe lighter
Thanks. Guess I will have to find one
Look for a Pro-X weighs 5.3 oz
Thanks
FWIW, they are a bit weight adjustable for those that like to tinker with "perfection." 
In all seriousness, no more than about 12 ounces has been a SAFE maximum after tons of testing. Lots of guns have shot well with both heavier and lighter tuners, though. Like I said, there are lots of variables. IMHO, chasing the "perfect weight" is a dead end and deep hole.
Thanks for the info. I will check it out. So Mike Do you think I would need a lighter tuner then the HarrelThey are a bit different but not vastly or anything. My method is heavily dependent upon two things....seeing top and bottom of a sine test and group shapes. IME, both are still there, just not as clearly as a less stiff bbl. All this is why I prefer a little heavier tuner but that's definitely not to say that more is better either. Yes, you can get too heavy at the muzzle. Also, fatter does not mean stiffer overall, automatically. Stiffer per in..certainly but overall, not necessarily. I actually think a 1 in straight is pretty sweet. Run the numbers through it and play with the barrel stiffness calculator that Dan Lilja has available. It's part of his bbl weight calculator but it'll give some interesting data for anyone interested. For example though, a 30" 1.250 straight is LESS stiff than a 21-22 inch Light Varmint contour bbl. Huge difference in weight too. Just check it out for yourself. Link to download it below.
Benchrest Barrel Weight Calculation Program - Lilja
Download the program free. A problem frequently encountered by the benchrest gunsmith when building a new rifle or rebarreling a rifle is determining where to trim the new barrel blank to make the barrel and rifle the correct weight. Usually the other components of the rifle are weighed and the...riflebarrels.com
I edited my post before reading your comment but in a word, no. The weight of a harrels is very sufficient. Not too much and not too light. It's something that is pretty forgiving, really. At least until you get pretty extreme. Check out the link. There's a rhyme and a reason I post what I do. That link helps simply put 2 and 2 together a bit.
When you get a chance to play with that Lilja program, I hope you'll post your results. Just guessing here but I would NOT be surprised if your 27" long 1.000 straight is actually LESS stiff overall that some more common, say 24" x .875-.900 straights. Won't be drastically different either way and I think your results help put all this into perspective a lot. Bottom line, you lose stiffness much faster with length than you gain with diameter is all.
Thanks again
